There are three alleles controlling the ABO blood types. IA and IB are codominant genes so that the combination IAIB
  produces the AB blood type. The third allele, i, is recessive to the other two alleles. Indicate which of these parents could
  produce the given child:Parents
   Child Yes or No
  (a) A  AB B
  (b) A  O A
  (c) A  B O
  (d) A  AB O
  (e) A  AB B
  (f) B  B O
  (g) AB  AB A

Question 2

In a certain breed of chicken, an incomplete dominant gene controls color. The homozygous black (BB), when crossed
  with the homozygous splashed-white (bb), produces an intermediate gray color pattern referred to as blue. A second gene
  controls the shape of the comb. The dominant allele (R) produces rose, whereas the recessive allele (r) produces single.
  Give the F1 and F2 genotypic and phenotypic ratios of a cross between a true-breeding black with a single comb and a
  true-breeding splashed-white with a rose comb. What will be an ideal response?
